标题: SAS自定义函数 [打印本页] 作者: shiyiming 时间: 2007-8-23 19:17 标题: SAS自定义函数 SAS 9.1中的proc fcmp过程步就是可以用来自定义函数的
有兴趣的朋友可以一起探讨一下作者: shiyiming 时间: 2007-11-30 10:31 标题: Re: SAS自定义函数 Function/Subroutine Declarations
[code:1xs57qfa]proc fcmp outlib= sasuser.MySubs.MathFncs;

if in = 0 then inv = .;
else inv = 1/in;

function day_date( indate, type $ );
if type = "DAYS" then wkday = weekday(indate);
if type = "YEARS" then wkday = weekday(indate*365);

其次，把错误log贴上来看看，让大家看log分析才是好习惯。作者: shiyiming 时间: 2008-10-10 08:27 标题: to horse1 sometimes it's just that one double quotes become 2 single quotes after copy & paste
anyway, I may be wrong作者: shiyiming 时间: 2008-10-10 09:51 标题: Re: SAS自定义函数 我的SAS是9.1.3版的，下面是程序运行的log

4 length z $ 30;
5 x = '1234';
